Here's an article on details of After Effects CS6 GPU features and requirements (CUDA, OpenGL): http://adobe.ly/aftereffects_cs6_gpu
If a MacOS computer is equipped with a nonstandard video card (e.g., a modified and reflashed GTX570 or GTX580), will these cards be theoretically utilized by AE? I understand that it's unlikely that it'd have been specifically tested against, but just want to make sure it's not a situation where it's checking by device IDs to see if it's a specific, approved card rather than by performance capabilities.
If you read the article closely, you'll see that there are two very different categories of GPU features and checks against GPUs:
For the CUDA capabilities of the GPU-accelerated ray-traced 3D renderer, it's checking for a specific device.
For the OpenGL capabilites, it's checking for minimum versions for OpenGL and Shader Model, as well as amounts of VRAM.
what are the reqs for Mac (MVP - iMAc) .
Its not clear in the article you gave us.
I have MBP 15.4 2011 model with ATI 256 VRAM and imac 2010 ATI 512 VRAM and i cant get the ray trace 3d renderer to run (error in final quality).
As my previous post and the document that I linked to say, there are many GPU features in After Effects. Only one of them (GPU acceleration of the ray-traced 3D renderer) relies on having one of a specific set of Nvidia cards. The document that I pointed to also tells how to request that additional hardware be added to the list of GPUs that can provide that feature.
I'm just dealing with that sinking feeling you get when you reaize your expensive computer can't take advantage of the new feature that you're excited to use. The ray-tracing renderer feature was the main reason i signed up for creative cloud and it's a tough one to swallow for us indie filmmakers who don't really have the budget to upgrade to a new video card. I wish there was support for all the high-end cards that come standard with the Mac Pros. Can't have everything i guess.
Ya, it's stable and works fine, but it just takes FOREVER. It's hard to go back from multi-core rendering and the speed that's otherwise fantastic. CS6 is such a worthy upgrade, and i'll probably buckle and get an nvidia card.
I'm not sure if you've directly addressed this in the forums and I'm aware that, as a publicly traded company, you have to be careful what you can and cannot say about the future.
The situation I'm in is that I purchased a GTX 570 with the intention of starting to use Resolve, but I would also really like to be able to leverage CUDA accelerated ray-tracing in AE on my Mac Pro in OSX. I'm working on a project right now where I'm using this feature in my Boot Camp installation of Windows and it works like a champ. I would love to be working in OSX though.
Any info on future support for a wider variety of CUDA accelerated cards in OSX?
